View Full Version : Buffering Tree Store

6 Dec 2011, 12:12 AM
Hi All,

I need to create a Tree Grid to provide infinite scrolling. If I add a config property as 'buffered: true' to the Tree store and provide a dummy data of 1000 rows or more, the browser just hangs :s. Is there any known way of buffering the Tree Grid data?

I don't think any work has been done to support buffering trees internally.

We have a buffered tree going, possible implementation hints here : http://www.sencha.com/forum/showthread.php?129866-Support-for-Buffered-Tree&

i try this to implement - but it seem that it runs in your case cause you have a grid. When try to use it stand alone there is no "guaranteedrange"

I hope that 4.1 brings a buffered tree...
